Thread: 05 GP GT Resonator went out. Replacing with Glasspack (Cheaper) Recommendations?

cherry bomb glasspack 30in long or so.

i used a thrush glass pack, 32 inch for 25 bucks at auto zone. you want to get one thats 2.25 i/d.

i had a flange welded on the end of mine and slapped it in, but i also have after market pipes, not factory welded cat back. so if you cant weld, you;ll need a muffler shop to swap it.

like this. btw, this is exactly how a walker replacement res looks like, only 1/2 the cost.

the longer the better to fight the drone.

my res measured 30 inches tube to tube end, the new one was 32, but i cut off 2.5 inches for the flange to be welded on.

best to measure yours and go from there.

if you going to have a shop weld it in you can put in what ever size you want too.

im all stock with the glass pack and a new single stock replacement muffler set up, and its nice and quiet. thats what i was after, due to the fact these engines never sound good. it will never have that V8 sound.

Larger the GP, the quieter the exhaust.

A nicely toned setup that is decently quiet would be a 24"~ glasspack, stock piping, an aftermarket tip of your choice and a Dynomax Super Turbo muffler...or an SLP/Corsa/Borla Muffler.

Deleting the cat or getting a high flow unit would add some deepness to it as well...just keep in mind the larger the res, the less rasp you have.

Here is my setup on my SS : ZZP Plog, 3in DP, U bend delete, Res. delete, stock piping, Dynomax Super Turbo mufflers and Quad tips. It's not bad sounding at all. Not loud in cabin at all, and lil to no drone. A resonator makes it way too quite for my tastes, but to each his/her own. Video in link below was taken a few hours ago, so I appologize for the wind and the loud ass dog in the background lol.
